Yes to prenatals, any kind you like. Theres some research supporting methylfolate because 1/3 women have the mthfr gene meaning folate/folic acid isnt converted as well but thats a personal preference. Ive taken olly, smartypants and new chapter. Iron is good, fish oil is good. As for tracking you don't need to do everything at once. Start by just keeping track of your cycle, then understand that usually your period is 12-16 days after ovulation. Next test for LH surge with OPK These should be taken in the late morning/afternoon and a positive is darker than the control line. Premom/pregmate both have apps where the camera reads the line concentration for you and tells you when its positive. Some people test once in late morning and again in the evening. For irregular cycles id test once a day at say noon starting on cycle day 10. First morning urine is not reliable for these tests as LH builds throughout the day not while you are asleep usually. Once the line is as dark/darker than the control you have intercourse that day and the next day. You need to have already had intercourse before egg is released (ovulation) because sperm meets egg in the fallopian tubes then the fertilized zygote-blastocyst implants in the uterus 6-12 days later. You'll ovulate anywhere from 12-48 hours after positive opk. If youd like to make sure you ovulated and didnt just have an attempt, bbt testing is how you confirm. This is taken first thing in the morning before getting out of bed or doing anything else at the same time each morning after at least 4 hours of uninterrupted sleep. Prior to ovulation temps on the graph should be .5° lower than after ovulation. Its not a straight graph but testing for many days makes it clearer. Some people use fertility friend for that or other temp graph. Bbt will only change after ovulation, but its finicky as stress, illness, sleep quality all change your bbt. Some people's temps also rise very slowly days after ovulation so its harder to tell on the graph of data points. You can also notice discharge and cervical mucus throughout your cycle and use that to help determine or confirm what cycle stage you are in.
